You are in the process of authorizing your app in the Google Play Developer Console. You are following Google's documentation and you're stuck at Step 3c when it comes to generate a signing certificate fingerprint (SHA1): https://developers.google.com/games/...nt_id_settings

Then the following will help.


How to generate a signing certificate fingerprint (SHA1) on Windows:

1. Press [Win] + [X] and select Command Prompt

2. In the command prompt window type one of the following lines depending on your installation of Java:
Code:
cd C:\Program Files (x86)\Java\jre1.X.0_YY\bin
cd C:\Program Files\Java\jre1.X.0_YY\bin
cd C:\Program Files (x86)\Java\jdk1.X.0_YY\bin
cd C:\Program Files\Java\jdk1.X.0_YY\bin
and press [Enter]

3a. To generate the debug SHA1, in the command prompt window type:
Code:
keytool -exportcert -alias androiddebugkey -keystore path-to-your-debug-keystore -list -v
and press [Enter]

3b. To generate the release SHA1, in the command prompt window type:
Code:
keytool -exportcert -alias alias-of-your-key -keystore path-to-your-production-keystore -list -v
and press [Enter]

4. Type the password associated to the keystore and press [Enter] (the default password for the debug keystore is: android).

5. Highlight and copy the SHA1

6. Paste the SHA1 in the relevant field of:
Google Play Developer Console > Game Services > Your App > Linked Apps > Step 2: Authorize your app screen
